  • Patent number: 7603800
    Abstract: An iron comprising a sole plate and a heating body (2) provided with a heating element (201), wherein the heating body (2) includes a first steam chamber (210) used for ordinary ironing, and a second steam chamber (220) used to provide extra steam when the iron is in a horizontal position, or a steam jet when the iron is in a vertical position, and liquid is supplied to said second steam chamber (220) by means of a pump manually operated by the user and combined with a steam circuit (223) ending in a set of vapour outlets in the sole plate, characterised in that when the iron is held in a vertical position, the second steam chamber (220) operates as a boiler-type steam generator, and in that when the iron is in said vertical position, the shape of the second steam chamber (220) is such that the liquid injected by the pump can be retained prior to vaporisation.

  • Patent number: 6807756
    Abstract: The invention relates to an iron (1) comprising a container of water (2) at atmospheric pressure. The water from the container flows through a nozzle between said container (2) and a heated and regulated steam chamber (5). An iron sole plate (3) forms the ironing surface and steam outlet holes (12) are arranged in said sole plate (3). The invention is characterized in that the iron (1) comprises means for creating a resonance or relaxation vibration in the water and steam circuit. The cyclic variation in the steam pressure is automatically maintained at an average pressure above that corresponding to the column of water available in the iron.
